The invention provides phenol ethers of the formula: ##STR1## wherein R is branched C.sub.3-4 alkyl, C.sub.3-4 cycloalkyl, branched cyano(C.sub.3-4 alkyl), phenyl(C.sub.2-3 alkyl), halophenyl(C.sub.2-3 alkyl), (C.sub.1-4 alkoxy)phenyl(C.sub.2-4 alkyl), or (C.sub.1-4 acyl)amino(C.sub.1-4 alkyl), alk is C.sub.1-4 alkyl substituted by a 3 to 6 membered cycloalkyl group, X is --O--, --S-- or --SO.sub.2 --; and R.sub.1 is --C.sub.1-4 alkyl- or --C.sub.1-4 alkoxy-, in their racemic and optically active forms, and their addition salts with pharmaceutically acceptable acids. These compounds are useful in therapy as .beta.-adrenergic blocking agents. Intermediates are also provided.
本发明提供了以下式子的苯醚: ##STR1## 其中R为支链C.sub.3-4烷基,C.sub.3-4环烷基,支链氰基(C.sub.3-4烷基),苯基(C.sub.2-3烷基),卤代苯基(C.sub.2-3烷基),(C.sub.1-4烷氧基)苯基(C.sub.2-4烷基),或(C.sub.1-4酰基)氨基(C.sub.1-4烷基),alk为C.sub.1-4烷基,其被3到6个成员环烷基取代,X为--O--,--S--或--SO.sub.2 --;R.sub.1为--C.sub.1-4烷基-或--C.sub.1-4烷氧基-,它们的外消旋和光学活性形式及其与药学上可接受的酸的加合物在治疗中作为β-肾上腺素能阻滞剂是有用的。本发明还提供了中间体。
